db6984c43c rte_update: Doesn't loop forever when multiple routes point to the same
destination.

dc7c7494e3 RIP _NOW_ actually talks to itself (workaround core bug: send data
from other port than we receive at), few FIXME's added.

756b86dea3 Learn static device routes from the kernel (temporary until we can make
such things configurable).

a0762910a6 Added pointer to network to RTE. The complications with passing NET separately
aren't worth 4 bytes per RTE.

rte_discard and rte_dump don't need net * as parameter.

7d83290780 Generate router_id automatically if possible (standard "smallest of local
regular interface addresses" rule).

Protocols should NOT rely on router_id existence -- when router ID is not
available, the router_id variable is set to zero and protocols requiring
valid router ID should just refuse to start, reporting such error to the log.

0804525255 Basic kernel routing table syncing implemented. Learning of routes installed
by other programs or the kernel itself is not supported yet, but it's not
needed for development of other protocols.

567e6c6220 Use (SOCK_DGRAM,IPPROTO_IP) socket instead of (SOCK_STREAM,IPPROTO_TCP).
This is exactly what Linux ifconfig does and seems to be the preferred way.

4c45595e3b o FIB flags now available for FIB users.

ab3a76a382 Added ipa_from_u32 and ipa_from_u32 for use in the kernel sync code (IPv4 only).
Don't ever think of using it in routing protocols.

7e7790c61f Since almost every UNIX system requires different techniques for reading
the kernel routing table as opposed to modifying it which is approximately
the same on non-netlink systems, I've split the kernel routing table
routines to read and write parts. To be implemented later ;-)

5b22683d2f After contemplating about RIP route timeouts for a long time, I've implemented
protocol callbacks for route insertion and deletion from the central table.
RIP should maintain its own per-protocol queue of existing routes, scan it
periodically and call rte_discard() for routes that have timed out.

7f3d198df1 Each protocol now hears even its own routes and needs to make its own
loop detection. This is needed since both RIP and OSPF handle multiple
neighbors and they need to redistribute routes learned from each neighbor
to the remaining ones.

47b793064c Solve chicken-and-egg problems with protocol startup. We now queue all inactive
protocols and don't send route/interface updates to them and when they come up,
we resend the whole route/interface tables privately.

Removed the "scan interface list after protocol start" work-around.

d92882be9b WALK_LIST_DELSAFE now actually works (it really couldn't since it didn't
reference list head at all).

c93214d442 o There are cases when SIOCGIFINDEX is defined, but it doesn't work. When
this happens, don't reject the whole interface, just mark it as index 0.
o  Removed Pavel's comment about EFAULT and SIGSEGV. EFAULT is a valid return
   code for cases where the buffer is too small.
o  Commented out the smart interface list size logic temporarily as it seems
   Linux 2.0 SIOCGIFCONF doesn't react to ifc_req==NULL sanely. Replaced it
   by exponential stepping.

fdf33cde1c Strange, on atrey ioctl() does not fill structure, and bird segfaults
on it. Now we "only" die().

Rip now uses main routing table properly: entries are stored directly
into main routing table and we are relying on core to call our's
compare. That unfortunately broke garbage collecting (and probably
many more things). It compiles.

786d0bb9e7 Added ipa_class_mask() which guesses netmask for classful addressing.
For pure A/B/C class addresses it just returns the class netmask, for
subnets it tries to guess subnet mask. Please make sure the address
you pass to this function is really a valid host address (i.e., call
ipa_validate() first).
